To evaluate the effectiveness of an educational intervention for parents of first year high school students in the State of Morelos, Mexico, whose aim was to impact adolescents' sexual behavior, knowledge and access to contraception.
Quasi-experimental prospective study with eleven control and eleven intervention schools using self-administered questionnaires for parents and adolescents pre- and post-intervention. Parent-child dyads in the control and intervention schools were matched according to parents' propensity score; the average treatment effect (ATE) was estimated for adolescent's outcome variables.
At follow-up, we found significant differences for adolescents in the intervention schools: 6.8% delayed initiation of sexual intercourse, 14.4% had correct knowledge about emergency contraception (EC), and 164% reported having received condoms from their parents, when comparing with students in control schools.
Our results suggest that parent-focused interventions could be an innovative and effective strategy to promote adolescents sexual health.
评估针对墨西哥莫雷洛斯州一年级高中生家长的教育干预措施的效果，该干预措施旨在影响青少年的性行为、知识和避孕措施的获取。
采用准实验前瞻性研究，十一所对照学校和十一所干预学校使用家长和青少年在干预前后自我管理的调查问卷。根据父母的倾向得分对对照和干预学校的亲子对子进行匹配；估计青少年结果变量的平均处理效应（ATE）。
随访时，我们发现干预学校的青少年有显著差异：6.8%的人延迟了性行为的开始，14.4%的人对紧急避孕（EC）有正确的认识，164%的人报告从父母那里收到了避孕套，与对照学校的学生相比。
我们的结果表明，以家长为重点的干预措施可能是促进青少年性健康的一种创新和有效的策略。
